* [metafieldsSet](/docs/api/customer/2024-10/mutations/metafieldsSet) Sets metafield values. Metafield values will be set regardless if they were previously created or not.

Allows a maximum of 25 metafields to be set at a time.

This operation is atomic, meaning no changes are persisted if an error is encountered.

As of `2024-07`, this operation supports compare-and-set functionality to better handle concurrent requests.
If `compareDigest` is set for any metafield, the mutation will only set that metafield if the persisted metafield value matches the digest used on `compareDigest`.
If the metafield doesn't exist yet, but you want to guarantee that the operation will run in a safe manner, set `compareDigest` to `null`.
The `compareDigest` value can be acquired by querying the metafield object and selecting `compareDigest` as a field.
If the `compareDigest` value does not match the digest for the persisted value, the mutation will return an error.
You can opt out of write guarantees by not sending `compareDigest` in the request.
